. T at whom it may concern:

invention.

Be it known that I, JAMES H. BOYD, a citi-E zen of the United States ofAmerica, residing at Waterville, in the county of Douglasand' State of.Washington, have invented a new and useful Hydraulic Motor, of whichthe following is a specification. I

My invention relates to hydraulic motors;

and has for its object to provide a'simple and efiicient device adaptedto utilize the power of a current or tide, and provided with meanswhereby it may be anchored or otherwise fixed in mid-stream.

Further objects and advantages of the invention will appear in thefollowing description and the novel features thereof will beparticularly pointed out in the claim.

Referring to the drawingsz-Figure 1 is a perspective View of a motorembodying my Fig. 2 is a plan view. Fig. 3 is a slde view. Fig. 4 is afront View. Fig. 5 is a detail plan view of the clutch-device. Fig. 6.1s a detail view in perspective of one of the shoes which are, attachedto the boats.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawlngs. I

- 1 designates twin boats spaced apart and held at the desired intervalby interposed framing 2, consisting of the X-shaped or bridge braces 4,the transverse tie-beams 5, and the longitudinal supporting bars 6 whichare preferably disposed above the plane of and rest upon said X-shapedor bridge braces with their upper. sides in the plane of the-tiebeams.This framework, including the boats, is floored over to form the sideplatforms 7 and the end platforms 8. The side platforms are providedwith cleats 9 for the attachment of the extremities of spars 10 by meansof cords or lashings 11, said spars being secured at their outer orremote extremities to stationary objects upon the shore, or to suitablepiles, not shown, to prevent the structure from swinging inward ortoward the shore. Bow and stern lines or cables 12 and 12 are alsoemployed for connection with stationary objects, and which in connectionwith said spars, hold the structure in the desired position withrelation to the current or direction of movement of the water to beutilized.

The front ends of the boats are provided with shoes 13, having the longbeveled or rounded inner sides 14, which converge toward their rear endsin order to concentrate the current between the boats. These shoes areheld in place by means of the ears 15, which bear upon the uppersurfaces of the platforms forming the tops of the boats adjacent to thebows ofthe latter. It will be seen that the inner sides of the boats aredeeper than the outer sides thereof in order to set more deeply in thewater to prevent the deflection or lateral dispersion of the volume ofwater which flows between the boats. Secured to the boats near theirfront ends. are the rear ends of the forwardly extending spars 16, whichare connected at their front ends and rest upon the surface of thewater, thus forming a dbris guard and prevent floating objects fromentering the space between the boats.

Mounted upon each boat or floating member is a side frame 17, and asthese frames are identical in construction the specific description ofone will be sufficient.

18 represents an upright, and 19 an adjacent rearwardly inclined bracearranged in front of the upright and connected to the up- 23 is anapproximately horizontal beam arranged longitudinally of the boat withits front end approximately in the plane of the upper end of thestandard, and it is supported at intervals by the uprights 24 and theinclined brace 25.

Mounted in the bearings 22 at the upper ends of the standards is atransverse spindle 26 carrying the drums, 27, and 28 representssupporting cables which are secured at one end to the frame, preferablythe adjacent ends of the beams 23, and attached at the other end to thedrums 27.

29 represents a drive-shaft mounted in suitable bearings 30 on one ofthe boats, and pivoted to the frame-work at a point3l slightly inadvance of said shaft is alever 32., A corresponding lever 32 is pivotedto the framework on the other boat, and both levers are provided attheir front ends with anti-friction rolls 33, around which pass theloops of the supporting cables 28.

34 represents a water-wheel approximately equal in width to the intervalbetween the inner sides of the boats and provided with the spacedblades, the shaft 36 of said wheel being mounted loosely in bearings 37in the levers 32. A sprocket wheel 38 is fixed to the water-wheel at oneend concentric with its shaft, and is connected by means of a chain 39with a sprocket pinion 40 on the driveshaft 29, whereby the rotarymotion of the wheel is conveyed to the drive-shaft.

41 represents a fly-wheel and 42 a beltwheel, which are fixed to thesaid drive-shaft, the latter being designed to carry a belt to conveymotion to suitable machinery.

Loosely mounted upon the shaft of the wa-' ter-wheel is a sprocket-wheel43 connected by a chain 44 with a similar sprocket-wheel 45, which isfixed to the transverse spindle 26;

and 46 represents a clutch, which may be of any suitable or preferredconstruction, and is provided with an operating handle 47,

whereby it may be thrown into and out of' connection with the loosesprocket-wheel 43 to secure the latter to the shaft of the waterwheel orallow said shaft to rotate loosely therein. When the sprocket-wheel 43is fixed by, the adjustment of the clutch to the shaft of thewater-wheel the rotary motion thereof is communicated through the chain44 and the sprocket-wheel to the spindle 26, thereby turning the drums27 and winding the supporting cables 28 thereon to elevate the frontends of the supporting levers 32, and hence lift the water-wheel out ofthe current. Adjacent to the sprocket-wheel 45 and fixed to the spindle26 is a brake-wheel 48, around which passes a brake-strap 49 fixed atone end to a suitable portion of the framework and connected at theother end to abrakelever 50. By means of this brake mechanism thewater-wheel may be lowered as slowly as may be expedient after thedisconnection of the clutch from the sprocket-wheel 43. While thesprocket-wheel 43 is locked to the shaft of the water-wheel the inertiaof thelatter is suflicient to prevent the rotation of the drums and thelowering of the water-wheel.

The operation of the above mechanism will be obvious from the abovedescription, and it will be understood that the elevation of thewater-wheel to withdraw it from the current is accomplished by the powerof the wheel acting through connections consisting of thesprocket-wheels 43 and 45 and the chain 44 when the first namedsprocket-wheel is secured to the shaft of the water-wheel by means ofclutch mechanism.

It will be understood, furthermore, that the elevation of thewater-wheel may be varied to cause it to dip more or less into thewater, and may be held at any desired elevation by means of thebrake-mechanism, for which suitable locking devices, not shown, may beprovided. a

Guards 51 are arranged at opposite ends of theframework at the innersidesof thefront and rear platforms to prevent operatives from coming incontact with the revolving wheel.

Variouschanges in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit of theinvention or sacrificing any of the advantages thereof.

Having described my. invention. what I claim is- In a device of theclass described, the combination with twin spaced floating members andsupporting frames" carried thereby, of bearing levers fulcrumed to saidsupporting frames, a water-wheel having its shaft mounted in bearingscarried by said levers, a driveshaft operatively connected 4 with thewaterwheel, a rotatable spindle carrying drums, cables fixed to theframework, passing around anti-friction rolls onthe extremities of thebearing-levers, and reeled uponsaid drums, sprocket-wheels arrangedrespectively upon the spindle and the shaft of the water-wheel, one ofsaid sprocket-wheels being loose, a chain connecting saidsprocket-wheels, a

clutch-device for locking the loose sprocketwheel to its shaft, and abrake mechanism connected with the said spindle,substantially asspecified.

JAMES H. BOYD.
